CHARLES A. MERRILL, OF BATTLE GREEK, MICHIGAN.

SPOKE-DRIVING MACHINE.

SPECIFICATION forming part of Letters Patent No. 224,026, dated February 3, 1880.

' Application filed June 27,1879. 1

To all whom it may concern:

Be it known that I, CHARLES A. MERRILL, of Battle Creek, inthe county of Calhoun and State of Michigan, have invented an Im provement in Spoke-Driving Machines, of which the following is a specification.

The nature of this invention relates to oer tain new and useful improvements in that class of machines particularly designed for driving spokes into wheel-hubs.

The object of my invention is to provide a machine that shall be capable of driving spokes of various lengths and at such a dish as may be desired.

The invention consists in the peculiar construction and arrangement of the various parts, all as more fully hereinafter set forth.

Referring to the drawings, Figure 1 is a perspective view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a vertical crosssection, showing locking device for securing the hub to the front end of the machine.

In the accompanying drawings, which form a part of this specification, W represents a suitable frame, the front end of which is inclined as shown, and in this end is secured the cross-head O. F isa bifurcated standard, which is sleeved upon the rod to between the forward ends of the base timbers of the frame. Adjustahlyseoured to the upper end of this standard is block E, in the upper end of which is rigidly secured the arm L. Upon this arm is slipped a hub, M, which has been previously mortised, and the end of the arm is passed through the slotN in 'thehead-block O, inwhich position it is retained by a link, 0, which engages with a notch, b, in the end of the arm, said link being operated by a lever, 1?. A spoke, Q, is then inserted in one of the mortises in the hub, the upper end of the spoke being held in proper position by the hooked lever S, which is pivoted to the plate R, against the face of which the spoke rests. This plate R has a lateral adjustment upon the upwardly projecting ends of the frame by means of suitable slots and. setscrews, as shown. This lateral adjustment is for the purpose of projecting or retracting the face or edge of the plate R, so as to govern the dish of the wheel, as may be desired.

I At the rear end of the machine is journaled in proper boxes the main shaft Z, which is driven by any convenient power. Upon this shaft is secured,in the usual manner, a clutchbox, the loose member of which has rigidly secured to it a cam, A, the face of which, as it is revolved, comes in contact with the face of a similar cam, B, which is sleeved upona rod, Y, just in advance of the shaft Z. To ,this cam B is secured the long arm of a V-spring, G, by means of the stirrup H, the opposite end of the spring being rigidly secured to the hanger D. The short arm of this spring G comes in contact with the face of an irregular cam, J, secured upon the shaft U, which is as shown.

By this means I am enabled to regulate the force of the blow to be given upon the end of the spoke by the mallet X,the handle of which is secured to the side of the cam B.

A leaf-spring, I, secured at one end to the side of the frame, its free end coming in contact with the upper end of the cam B, raises the mallet-head above the end of the spoke.

What I claim as my invention is 1. In a machine for driving spokes, substantially as described, the mallet X, rigidly secured to a cam, B, sleeved upon a rod or shaft, Y, said mallet and cam being actuated by a revolving cam,'A, both cams A and B having curved frictional contact-faces, substantially as and for the purposes described.

2. In a spoke-driving machine, a V-spring,

G, the long arm of which is secured to the cam which carries the mallet, in combination 6 journaled in proper 'bearin gs across the frame, said shaft and cam being operated by a lever,
